Abstract

The present invention relates to an electrodeposition material for the electrochemical deposition of a corrosion-protective layer of TiO2 on an electrically conductive substrate comprising a titanium compound, a complexing agent, water and optionally an accelerator, organic solvents, buffering agents and one or more additives, characterized in that the titanium compound is titanyl sulfate and/or titanyl oxalate, the complexing agent is selected from the group consisting of gluconic acid, gluconates, polyhydroxy-polycarbonic acids, ethylenediaminetetraacetate, methylglycinediacetate, iminodisuccinate, nitrilotriacetic acid and nitrilotriacetate, triethanolamine, phosphonic acid and phosphonates, poly-aspartic acid and polyaspartates, polyacrylic acid and polyacrlylates and the accelerator is selected from the group consisting of hydroxylamines and their derivates, nitrates, H2O2 and organic peroxides. The invention further relates to a process for providing a corrosion-protective layer of TiO2 on an electrically conductive substrate and to a metal substrate coated with a layer of TiO2.
